When I saw cucumbers on sale for 3 for $1, I just couldn’t resist. I knew I’d figure out a way to preserve them later—and that’s exactly what I did. The first option that came to mind was to freeze cucumbers. Freeze cucumbers you say?! Yes, it’s easy, and it works well, with a few caveats. But I’m getting ahead of myself.

Cucumbers tend to go bad quickly, so I didn’t want to wait too long. I decided to preserve them in two ways: freezing and dehydrating. In this post, I’ll walk you through how to freeze cucumbers, step by step. (I’ll be writing separate posts on dehydrating cucumbers and making pickles with dehydrated, so be sure to check back soon—or better yet, follow my blog so you don’t miss out!)

It’s super easy to freeze cucumbers, but there are a few things you’ll want to know to ensure success.

Step 1: Before Freezing Cucumbers, Wash them!

Just like with any produce, it’s important to give your cucumbers a good wash before freezing them. Even if they look clean, rinsing helps remove any dirt, wax, or bacteria.

Pro tip: I love using this over the sink colander (Amazon). Since it hangs above the sink, I don’t end up with whatever I’m rinsing sitting in water.

Step 2: Dry the Cucumbers Thoroughly

After washing the cucumbers, I patted them dry. You can definitely use paper towels, but I personally prefer flour sack towels because they’re more absorbent and reusable. Plus I find that I have a ton of other uses for them, so I’m happy to have them on hand.

Step 3: Slice the Cucumbers

Next, I sliced the cucumbers into fairly thick rounds—somewhere between 1/3″ and 1/2″ thick. I opted for thick slices because I can fit more on the tray that way.

Step 4: Flash Freeze the Cucumber Slices

To prevent the slices from clumping together, I spread them out in a single layer on a baking sheet lined with parchment paper (Amazon). Then I popped the tray into the freezer for about 3 hours.

You don’t need to freeze them completely solid—just enough so they won’t stick together when you store them.

Step 5: Transfer the Flash Frozen Cucumbers to Freezer Bags

Empty labeled freezer bags. It's easier to label them before filling them with the frozen cucumbers. — Label your freezer bags with the date and contents. It’s easier to label the bags before filling them.

Once partially frozen, I placed the cucumber slices into labeled Ziploc freezer bags. You could also use a vacuum sealer if you have one and want to prevent freezer burn for long-term storage. I use this vacuum sealer (Amazon) with mason jars when I want to freeze cucumbers more than a month or two.

How to Use Frozen Cucumbers

Because cucumbers have such a high water content, they will be soft or even mushy once thawed. While that makes them less than ideal for salads or fresh eating, there are still plenty of great ways to use them:

Smoothies: Add frozen cucumber slices to green smoothies for a refreshing, hydrating twist. This is my favorite way to use them, since I make smoothies for our breakfast every morning.
Gazpacho or cold soups: Dice before freezing for easier use later.
Infused water: Use frozen cucumber slices in your water bottle for a refreshing, almost zero calorie drink.
Juicing: Blend them straight from the freezer for a nutrient-packed juice.
Skincare: Use thawed slices to soothe puffy eyes or irritated skin.
Salad dressing or dips: Thaw frozen cucumbers and drain off any water and pat them dry before blending them into homemade salad dressing or dips.

📝 Pro tip: If you know how you plan to use them, consider dicing or blending the cucumbers before freezing! For instance, if you want to use your frozen cucumbers to make gazpacho, you may want to dice them instead of slicing before freezing. If you’re unsure, it’s always a good idea to do a few variations.

Final Thoughts

Freezing cucumbers is a fast and easy way to preserve them, especially when you find a great deal at the store or harvest a bumper crop from your garden. While they won’t be crisp after thawing, frozen cucumbers still have plenty of practical uses.

If you’ve got cucumbers to spare, I highly recommend giving freezing a try. And stay tuned—I’ll be sharing how I dehydrate cucumbers next, including how I turn them into crispy, flavorful pickles!
